In S401, power control information of a physical uplink shared channel (PUSCH) is obtained.
In the embodiments of the present invention, step S401 may be implemented in any one of the embodiments of the present invention, which is not limited in the embodiments of the present invention, and will not be repeated here.
In S402, a power adjustment value corresponding to a transmitting power of the PUSCH is determined according to the power control information. The power adjustment value includes at least one selected from: a path loss compensation power value; an initial power component value; a dynamic power adjustment value, the dynamic power adjustment value including an accumulated power value or an absolute power value; and a dynamic power added value.
In an implementation manner, the determined power adjustment value corresponding to the transmitting power of the PUSCH includes the path loss compensation power value. At this time, the power control information includes signal information configured to calculate the path loss compensation power value, and the path loss compensation power value may be determined according to the signal information configured to calculate the path loss compensation power value.
Optionally, the path loss compensation power value may be determined according to a path loss value measured by a reference signal corresponding to an identifier of a reference signal configured to calculate the path loss compensation power value. It can be understood that the reference signal configured to calculate the path loss compensation power value is configured to measure the path loss value, and the path loss value is configured to calculate the path loss compensation power value. An identifier may be preset for the reference signal configured to calculate the path loss compensation power value, and thus different reference signals configured to calculate the path loss compensation power values can be distinguished from each other. The identifier of the reference signal configured to calculate the path loss compensation power value includes at least one of: an SSB identifier; and a channel state information reference signal (CSI-RS) identifier.
Optionally, determining the path loss compensation power value according to the path loss value measured by the reference signal includes determining a product value of the path loss value measured by the reference signal and a path loss compensation factor as the path loss compensation power value. The path loss compensation factor may be set according to actual conditions, and is not limited herein.
In an implementation manner, the determined power adjustment value corresponding to the transmitting power of the PUSCH includes the initial power component value. At this time, the power control information includes the configuration information of the initial power component value, and the initial power component value may be determined according to the configuration information of the initial power component value. Optionally, the initial power component value included in the configuration information of the initial power component value may be determined as the initial power component value. Alternatively, a sum value of the nominal power component value and the terminal-specific power component value included in the configuration information of the initial power component value may be determined as the initial power component value.
In an implementation manner, the determined power adjustment value corresponding to the transmitting power of the PUSCH includes the dynamic power adjustment value, and the dynamic power adjustment value includes the accumulated power value or the absolute power value. At this time, the power control information includes the indication information of whether to allow a cumulative power adjustment, and the dynamic power adjustment value may be determined according to the indication information of whether to allow the cumulative power adjustment.
Optionally, when the dynamic power adjustment value is determined to be the absolute power value according to the indication information of whether to allow the cumulative power adjustment, the absolute power value may be determined according to a transmit power control (TPC) command of a network device. It can be understood that the network device may send the TPC command to the terminal device, and correspondingly, the terminal device may receive the TPC command and determine the absolute power value according to the TPC command. For example, the TPC command may carry the indication information of the absolute power value, and the indication information includes, but is not limited to, an adjustment value of the absolute power value, and the absolute power value may be determined according to the adjustment value of the absolute power value included in the TPC command.
Optionally, when the dynamic power adjustment value is determined to be the accumulated power value according to the indication information of whether to allow the cumulative power adjustment, the accumulated power value is determined according to a sum value of a dynamic power adjustment value of a previous transmission and an absolute power value of a current transmission.
Optionally, when a first preset condition is satisfied, a rollback process is performed on the dynamic power adjustment value. Performing the rollback process on the dynamic power adjustment value refers to adjusting a dynamic power adjustment value of the current transmission to the dynamic power adjustment value of the previous transmission. The first preset condition may be set according to the actual conditions. For example, the first preset condition includes at least one selected from: receiving a connection release message; receiving a connection refused message; receiving indication information of entering an idle state; and receiving feedback information of successfully receiving data sent by the network device. Therefore, the method may perform the rollback process on the dynamic power adjustment value when the first preset condition is satisfied.
Optionally, when the first preset condition is satisfied, an initialization process is performed on the dynamic power adjustment value. Performing the initialization process on the dynamic power adjustment value refers to setting the dynamic power adjustment value as an initial value. The initial value may be set according to the actual conditions, for example, may be set to 0. Therefore, the method may perform the initialization process on the dynamic power adjustment value when the first preset condition is satisfied.
For example, as shown in FIG. 5, a terminal device sends uplink data to a network device via PUSCH-1 at a moment t1, and starts a feedback receiving timer (such as a feedback timer), and the terminal device receives retransmission scheduling downlink control information (DCI) signaling from the network device for the PUSCH-1 at a moment t2. The DCI signaling carries indication information of a dynamic power adjustment value, and the terminal device determines the dynamic power adjustment value according to the indication information of the dynamic power adjustment value included in the DCI signaling, adopts the determined dynamic power adjustment value to retransmit the data (which has been transmitted via the PUSCH-1) at a moment t3, and adopts the determined dynamic power adjustment value to send uplink data to the network device via PUSCH-5 at a moment t4. At a moment t5, the terminal device receives a connection release message of a radio resource control (RRC) signaling, and performs a rollback process or an initialization process on the dynamic power adjustment value.
In an implementation manner, the determined power adjustment value corresponding to the transmitting power of the PUSCH includes the dynamic power added value. At this time, the power control information includes the configuration information of the dynamic power added value, and the dynamic power added value may be determined according to the configuration information of the dynamic power added value.
Optionally, the dynamic power added value is determined according to a product of a power value added per time and a number of power additions in the configuration information of the dynamic power added value.
Optionally, when a second preset condition is satisfied, the dynamic power added value is determined. Therefore, the method may only determine the dynamic power added value when the second preset condition is satisfied, and at this time, the power adjustment value corresponding to the transmitting power of the PUSCH includes the dynamic power added value. Otherwise, when the second preset condition is not satisfied, the dynamic power added value is not determined, and at this time, the power adjustment value corresponding to the transmitting power of the PUSCH does not include the dynamic power added value.
The second preset condition may be set according to actual conditions, for example, the second preset condition includes retransmitting transmitted data.
Optionally, retransmitting the transmitted data includes at least one selected from: retransmitting the transmitted data on a PUSCH with a same configure grant (CG) resource as a previous transmission; retransmitting the transmitted data by using a same hybrid automatic repeat request (HARQ) process as the previous transmission; and retransmitting the transmitted data by using the same HARQ process as the previous transmission on the PUSCH with the same CG resource as the previous transmission.
Optionally, when a third preset condition is satisfied, a rollback process is performed on the dynamic power added value. Performing the rollback process on the dynamic power added value refers to adjusting a dynamic power added value of a current transmission to a dynamic power added value of a previous transmission. The third preset condition includes at least one selected from: receiving a connection release message; receiving a connection refused message; receiving indication information of entering an idle state; and receiving feedback information of successfully receiving data sent by the network device. Therefore, the method may perform the rollback process on the dynamic power added value when the third preset condition is satisfied.
Optionally, when the third preset condition is satisfied, an initialization process is performed on the dynamic power added value. Performing the initialization process on the dynamic power added value refers to setting the dynamic power added value as an initial value. The initial value may be set according to the actual conditions, for example, may be set to 0. Therefore, the method may perform the initialization process on the dynamic power added value when the third preset condition is satisfied.
According to the method for determining the power parameter in the embodiments of the present invention, the power control information of the PUSCH is obtained, and the power adjustment value corresponding to the transmitting power of the PUSCH is determined according to the power control information. The power adjustment value includes at least one selected from: the path loss compensation power value; the initial power component value; the dynamic power adjustment value, the dynamic power adjustment value including the accumulated power value or the absolute power value; and the dynamic power added value. Therefore, the terminal device may determine the power adjustment value corresponding to the transmitting power of the PUSCH according to the power control information, so that the transmitting power of the PUSCH may be adjusted according to the power adjustment value corresponding to the transmitting power of the PUSCH. The transmitting power of the PUSCH may be flexibly and accurately adjusted, which improves the reliability of the transmission on the PUSCH of the terminal device, and reduces the power consumption of the terminal device.
